I have a usb flash drive and according to sources I found out after the fact that I should have used ext2 instead of ext4 due to the extra write operations.
Is it possible to convert the ext4 root partition to ext2 or do I need to backup, reformat, and restore?
I'm on Slackware-current and I've got a /dev/sda1 (the root partition) formatted as ext4. The output of /etc/fstab is:
Code:
/dev/sda2 swap swap defaults 0 0
/dev/sda1 / ext4 defaults 1 1

I'm trying to convert big ext4 partition to logical. I was able to do that with Arconis Disk Director Home 11 with swap and ext3 partition, but it doesn't recognize ext4.
Unfortunately I can't copy 2TB data to another HD Now I have:
Pri /boot ext3
Log / ext3
Log swap swap
Pri /media/X ext4 <- 2TB

I got a problem booting ubuntu 10.4 RC but i solved it by replacing root partirion uuid in grub boot menu then I disapled totally uuid passing to linux from /etc/default/grub . but something else i noticed why grub choosed insmod=ext2 why not ext4 specially I use now ext4 .I tried by editing the grub boot menu replacing "insmod=ext2" by "insmod=ext4" it booted and the three lines error during booting that i used to see them science ubuntu 9.10 totally disappeared . really I dont understand can anybody explane for me.and if what i did was right ,can anybody tell me how to make grub always and permenantly detect ext4 as ext4 not as ext2.

* ext4 partition accessible by root only.
* after entering my pass-phrase I get
Code: /dev/mapper/udisks-luks-uuid-***** uid1000 is mounted What I'm asking for is a way to create the ext4 file system without being attached to some UID and to be accessible by any user.

When I do that I be able to install Ubuntu Server next to CentOS. And I will add partition /home(ext4) for both and "/"(ext4) for Ubuntu.
I have a question, i accidentally formatted an lvm volume as ext2 after creating it. Then of course, we copied a ton of data to it before I realized it was ext2. (I guess ext2 was the default when using mkfs without a -t) Anyway - can I just use tune2fs -j on the LVM just like I would a /dev/sdx device?

View 7 Replies View RelatedWith the release of CentOS 5.5 ext4 is considered stable in this distribution so I decided to migrate to it. Luckily I started from migrating fresh server with CentOS 5.5 using some instruction I found on the internet. I think I shouldn�t say, that I screwed the whole thing up ;) After about 6 hours cursing, kicking, and crying I solved the task and figured the correct sequence of actions. The small problem with migrating root partition is that you can�t unmount it BTW.
During migration task, I found, that CentOS 5.5 rescue mode is somewhat broken a little in terms of ext4 support. It can mount ext4 partitions successfully. But its e2fsprogs package (tune2fs, e2fsck etc.) doesnt see ext4 partitions and say, that superblock is corrupted on a partition once is converted to ext4 (at least it did it for me. May be I should force filesystem type with -t ext4 switch?). Keep in mind, that if you screw your system up too badly, you will not be able to run tune2fs and e2fsck on it from rescue modeBut you will still able to mount it if it is not corrupted badly. In all below examples,Boot your system normally and login as root. Upgrade kernel if you wish (I usually use yum upgrade to upgrade all on new machines). Then upgrade/install some other packages
I run an upgrade and an update on a lucid lynx beta 2. --- got no problems. but about the filesystems i have some questions because it seems for me that at every system boot the system will run an fsck. somtimes it's shown up, somtimes not. but in /var/log/messages and in syslog
I have always following messages ( occured in beta 2 too ).
But first before i continue - here my disk layout:
And here my filesystem types:
This is my problem because those values are seems to be static ! ( note: this partiton is mounted but not in use ) and last not least: the drive is an external usb scsi disk. but on the other side lucid lynx is running fine on my box.
I'm having some problems with errors reported by fsck on my EXT4 root partition on my Ubuntu 10.10 installation... If I run fsck I get the following output:
Code:
# fsck -n /dev/sda1
fsck from util-linux-ng 2.17.2
e2fsck 1.41.12 (17-May-2010)
Attenzione! /dev/sda1 montato.

I want to install Ubuntu to a USB Flash drive (so I have my Desktop everywhere and can customize it as I want). I'm still choosing what's the best filesystem for the USB; Ext2 with no journaling or Ext4 with journaling but performance increase? I know that journaling will probably reduce the life of the USB flash drive dramatically, so is Ext2 the obvious choice? Or is it a bad idea to install Linux (Ubuntu probably) on a USB Flash drive? I tried running a live CD from the USB drive, but it wasn't very customizable - which is the point of carrying my OS with me.

View 1 Replies View RelatedI have a installation of Ubuntu on a flash drive that I just finished updating, etc. I noticed that it ran surprisingly slow during all my updates and software installations. I looked into it further and found out that for Flash Drive installations, it is recommended to use ext2 due to it's speed and lack of journaling (to limit the amount of writes to the disk).
I REALLY don't want to spend all the time and effort I have just spentt on reinstalling from scratch! I'd like to convert my partition filesystem from ReiserFS to ext2. How can I do this?
Can I backup all the information, do a new installation using the LiveCD, and restore the backup? What program can I use, and which directories do I need to backup?
I would like to convert my /tmp and /boot partitions from Ext3 to Ext2 on my Arch Linux setup. I don't see any use in having journaling for either partition. I want to make sure that I have the right steps lined up so could someone verify that this is correct (from a live cd):
Code:
#sudo tune2fs -O ^has_journal /dev/sda7
#sudo e2fsck /dev/sda7
#sudo tune2fs -O ^has_journal /dev/sda5
#sudo e2fsck /dev/sda5
I then edit /etc/fstab to reflect these changes (ext3 to ext2 for both lines)
Does it matter what order I do it in (/dev/sda7 is /tmp and /dev/sda5 is /boot).

View 4 Replies View RelatedCurrently I have a four partition setup: One ext4 /boot partition for Fedora, one LVM partition, one ext4 partition (which has Ubuntu), and one swap partition. What I would like to do is shrink down the ext4 partition which has Ubuntu on it and increase the size of my LVM parition (and increase the Volume Group, filesystem, etc. within the LVM). However, I've been searching on Google and the only solutions I find is to make the free/unpartitioned space and then create a new LVM partition and stretch the VG over the two LVM partitions. However, I already have 4 partitions, so I can't make the fifth one.
Is there any possible way I can increase the size of the underlying LVM partition itself?
I'm trying to set up my Fedora 15 installation to automatically mount (with all privileges needed for read/write access w/o a password prompt) an ext4 partition on the same HDD. Below is the output of sudo fdisk -l.

Partition table entries are not in disk order I'm trying to automount /dev/sda8, I believe. I'll check that when I've rebooted to by Ubuntu partition, 'cause that's where I know how to do it. I tried to use pysdm, since that's what I used to do the same thing in Ubuntu, but it wasn't found by the Fedora package manager.

I have been trying to install windows for 15 days and I was finally able to do it by removing in "disk utility" the sign saying that the fedora partition is bootable... but I did it when the partition was active... It showed me a message error but i thought that it told me it wasn't abvle to do it... and now that windows is installed I cannot any more access the partition either in rescue mode and on a live cd ... what could I do to access the partition either to save all the files or to (it woiuld be the best) reinstall the grub ?

I have installed grub.efi in the ESP partition which is able to load ubuntu 9.04.I think it works with fedora 11 x64 as well.

It says you need small ext3-formatted /boot partion and a ext4-formatted root partition. Does this configuration have to be setup before you boot into the live cd? If so, please tell me how to set this up. my pc is pentium d with 2 hard drives. The master hd is has xp, ubuntu8.04, and swap partitions. I would like to use one-half of the slave drive for f13.
Second question. I would like to be able to verify download of fedora-13-i686.iso. I downloaded it to my xp partition and installed Windows MD5summer. Where or how do i get the md5 file for this iso file?
i TOTALLY ****ed up my windows bootmgr, and, in some way, the linux partition too. I'd like to format the windows partition, but as all my info stays intact I'd like to conserve it that way. The only way I can think of, is to make a new ext2 partition on the same HDD y have windows ( I only have one HDD, so... ) and save the information there . Wich is the correct way to do so, without losing all my software and/or information??
Other details:
* Rright now, i don't have ubuntu installed on my pc ( I'm using a live cd ).
* I'm using ( or was ) win 7.
* The only partitions on my HDD is an ntfs ( 60 GB ) and an unallocated ( 240 GB )
I had to install a new disk drive in my PC a week ago because the old drive died. The new drive is a 160 gig drive. First I installed Win XP with S/P 3 and everything was fine. Then I installed Ubuntu 8.04 and the troubles began. Ubuntu resized the Windows partition down to 8.81 gig and used the other 137.44 gig for Ubuntu. When I booted into Windows I started getting nasty little messages about "not enough disk space". SOOoooo....... I booted using the Ubuntu install CD and ran "sudo gparted" in a terminal window. I tried to resize the ext2 partition but got an unknown error.
Then I ran fixmbr in Windows to get rid of grub. Then I tried running gparted again to delete the ext2 partition. Got an error that said "can't delete the partition because it's mounted". So I tried to unmount the partition but got a message that the command "unmount" could not be found. After that I installed Partition Magic in Windows and tried that. It sees the ext2 partition but says it's unsupported when I try to delete or resize it.
I ran fdisk but it doesn't see the Linux partitions either, so I can't delete them in that program. I finally tried to format the disk but now I have a 9 gig drive with nothing on it. How do I get those Linux partitions off the drive so I will have a 160 gig drive that I can start over with? I've spent 6 days this week reinstalling XP and all of my programs, and now everything is gone because Ubuntu decided to be a disk hog.
